By reducing the potential drop of a storage node that occurs due to feedthrough, the capacitance of a storage capacitor is reduced and sensor sensitivity is improved. In a photosensor, the first terminal of a storage capacitor (C2) and the gate of a MOS transistor (M1), which outputs a signal in accordance with the potential of a storage node (N2), are connected to the storage node (N2). A forward biased pulse voltage is supplied to the anode of a first photodiode (DS) in a reset period, and a reverse biased voltage is supplied to the anode of the first photodiode in a storage period and a readout period. A reverse biased voltage is supplied to the anode of a second photodiode (DM) in all operation periods. A voltage that keeps the potential of the storage node lower than the threshold value of the MOS transistor (M1) is supplied to the second terminal of the storage capacitor in the reset period and the storage period, and a voltage that thrusts the potential of the storage node (N2) upward to the threshold value of the MOS transistor (M1) or higher is supplied to the second terminal of the storage capacitor in the readout period.

In a digital broadcast system, when a channel is switched, for instance, on a receiving apparatus side, a digital processing is necessary, accordingly, a time until a next channel becomes viewable, that is, a blackout time is rather longer than ever. By paying attention to this point and inserting a CM during this period, the CM can be assuredly presented to the users. In addition, at the time of selection of one channel including a rise-time of a power source of the receiving apparatus or even at the time of system stoppage, the CM can be similarly presented, and furthermore the finding can be applied also to an ordinary analogue broadcast system. Thereby, picture displaying apparatus and receiving apparatus that can assuredly present commercial messages to users and a method of presenting the commercial messages is provided.

In a corrective tempering method and apparatus for a rolling element in which the thermal deformation of the rolling element is corrected within an extremely short time by utilizing plasticity exhibited during a metallic structure transforming process brought about by low-temperature tempering of the rolling element made of steel, the hardened rolling element is heated and pressured to a maximum temperature within a range of from 250 to 500.degree. C. by a heating device while set in correcting molds to correct the deformation of the rolling element at a degree of working within a range not exceeding an elastic deformation range of the rolling element at a room temperature. The rolling element can be heated also by an induction heating device in addition to a conduction heating device. A product whose inner/outer diameter correcting degree of deformation is 60% or more, dimension standardizing rate is 30% or more, surface roughness is less than Ra 0.2 .mu.m, and surface hardness is HRC 56 or more can be obtained for a correction time within 6 minutes and an induction heating time within 30 seconds.

Detection signals of respective photo sensor circuits (senS, senD, senON, and senOFF) are activated so as to be output at once for each group of prescribed plural number of sensor rows (LSk) by a row driver (6). Within the prescribed number of sensor rows (LSk), photo sensor circuits (senS, senD, senON, and senOFF) sharing the same power line (SL2, SL5, . . . ) between at least two different sensor rows (LSk) are included. The detection signals of the respective photo sensor circuits (senS, senD, senON, and senOFF) in the prescribed number of sensor rows (senS, senD, senON, and senOFF) are output via mutually different output lines (SL1/SL3, SL4/SL6, . . . ).

The invention concerns an automatic sorting apparatus for sorting out pieces under process, such as fish and shellfish or industrial products, into different size groups. In the prior art automatic sorting apparatus, pieces under process are readily caught in sorting holes, making it difficult to obtain smooth sorting. The invention permits smooth sorting. An automatic sorting apparatus to this end includes an endless conveyor having sorting holes and capable of excursion, an inner receiver disposed inside the endless conveyor for receiving pieces under process falling from the sorting holes, and an outer receiver disposed outside and below a U-turn portion of the endless conveyor for receiving pieces under process falling off the U-turn portion. Another automatic sorting apparatus includes two or more endless conveyors having different excursion diameters and disposed one inside another at an interval. The sorting holes of each endless conveyor are smaller than those of the next outer endless conveyor. An inner receiver is disposed inside the innermost endless conveyor for receiving pieces under process falling through the sorting holes of that endless conveyor. An outer conveyor is disposed outside and below a U-turn portion of each endless conveyor for receiving pieces under process falling through the sorting holes of that endless conveyor.

Provided is a display device having a photodetecting element in a pixel, and having an input function that is not dependent on light environments. This is a display device having an optical sensor in a pixel region. The optical sensor includes a first sensor pixel circuit that outputs a sensor signal corresponding to electric charges accumulated during an accumulation period in an ON time of a light source for the sensor; and a second sensor pixel circuit that that outputs a sensor signal corresponding to electric charges accumulated during an accumulation period in an OFF time of the light source. A sensor driving circuit for driving the first sensor pixie circuit and the second sensor pixel circuit supplies reset signals (RST1, RST2) to the first sensor pixel circuit and the second sensor pixel circuit, respectively, during vertical flyback periods in pixel display in the pixel region.

A display device includes a photosensor (81) in a pixel region (1) of an active matrix substrate (100). The photosensor (81) includes a photodetection element, reset signal wiring that supplies a reset signal RS to the photosensor (81), readout signal wiring that supplies a readout signal RW to the photosensor (81), and a sensor switching element for reading out the potential of the storage node to output wiring as sensor circuit output, the potential of the storage node having changed in accordance with the amount of light received by the photodetection element in a sensing period, the sensing period being from when the reset signal is supplied until when the readout signal is supplied. The potential of wiring having a parasitic capacitance with the storage node is fixed to a predetermined potential V0 at least either one of immediately before the readout signal RW and immediately before the reset signal RS.
